Validation for skill structure
Discovery
85%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a strong description that clearly articulates both capabilities and usage triggers with an explicit numbered list of scenarios. The main weakness is missing common user terminology like 'PowerPoint', 'slides', or 'deck' that would improve trigger term coverage.
Suggestions
Add common trigger term variations like 'PowerPoint', 'slides', 'slideshow', or 'deck' to capture more natural user language
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Creating new presentations', 'Modifying or editing content', 'Working with layouts', 'Adding comments or speaker notes'. Uses third person voice appropriately. | 3 / 3 |
Completeness | Clearly answers both what ('Presentation creation, editing, and analysis') and when ('When Claude needs to work with presentations (.pptx files) for...') with explicit numbered trigger scenarios. | 3 / 3 |
Trigger Term Quality | Includes 'presentations', '.pptx files', 'speaker notes', and 'layouts' as trigger terms, but missing common variations like 'PowerPoint', 'slides', 'slideshow', or 'deck' that users would naturally say. | 2 / 3 |
Distinctiveness Conflict Risk | Clear niche focused specifically on .pptx presentation files with distinct triggers like 'layouts', 'speaker notes', and 'slides' that wouldn't overlap with document or spreadsheet skills. | 3 / 3 |
Total | 11 / 12 Passed |
Implementation
85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a strong, comprehensive skill document that excels in actionability and workflow clarity. It provides concrete commands, detailed JSON schemas, and clear multi-step processes with validation checkpoints. The main weakness is some verbosity with repeated warnings and explanations that could be consolidated, though this doesn't significantly detract from usability.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is comprehensive but includes some redundant explanations and could be tightened. Repeated warnings like 'NEVER set any range limits when reading this file' appear multiple times, and some sections have verbose explanations that could be condensed. | 2 / 3 |
Actionability | Excellent actionability with concrete, executable commands throughout. Every workflow includes specific bash commands, Python scripts with exact syntax, and detailed JSON schema examples that are copy-paste ready. | 3 / 3 |
Workflow Clarity | Multi-step workflows are clearly numbered with explicit validation checkpoints. The editing workflow includes mandatory validation after each edit, and the template workflow has clear sequential steps with verification points like thumbnail generation for visual validation. | 3 / 3 |
Progressive Disclosure | Well-structured with clear sections for different use cases (reading, creating without template, editing, creating with template). References to detailed files like html2pptx.md and ooxml.md are clearly signaled and one level deep. | 3 / 3 |
